BRIEF RIDGING OVER THE REGION WILL PROVIDE WARM AND DRY CONDITIONS
THROUGH THE AFTERNOON BEFORE A SHORTWAVE TROUGH MOVES THROUGH.
THIS WILL BEGIN TO BRING SCATTERED SHOWERS TO SOUTH CENTRAL MT
LATE THIS EVENING, MOVING EAST THROUGH THE OVERNIGHT HOURS. ENERGY
BEING ADVECTED INTO THE REGION BEHIND THE MAIN TROUGHING IS
EXPECTED TO CREATE SCATTERED SHOWERS AND THUNDERSTORMS LATE
SATURDAY MORNING THROUGH THE EVENING. THUNDERSTORMS ARE EXPECTED
TO REMAIN ON THE WEAK SIDE WITH WEAK 0-6KM SHEAR AT 10-20KTS AND
MUCAPE AT 500 J/KG OR LESS. CONFIDENCE IS HIGH THAT RIDGING WILL
RETURN FOR SUNDAY THROUGH MID WEEK. A DISTURBANCE MOVING ACROSS
NORTHERN MT LATE SUNDAY INTO MONDAY WILL BRING A WEAK FRONT
THROUGH, BUT NO PRECIPITATION IS EXPECTED WITH THIS AND WINDS WILL
BE THE MAIN CONCERN (GUSTS 25-35 MPH). LATE WEDNESDAY INTO
THURSDAY, ENSEMBLES ARE EITHER TRYING TO BRING IN A PACIFIC
SHORTWAVE OR BRING UP MONSOONAL MOISTURE AND ENERGY FROM THE
SOUTHWEST. EITHER WAY THERE IS MODERATE CONFIDENCE ON SOME KIND OF
UNSETTLED PATTERN, BUT THE TYPE OF SET UP IS UNCERTAIN AT THIS
TIME.
HIGH TEMPERATURES WILL BE IN THE 60S SATURDAY, WARMING TO THE 70S
AND LOW 80S BY TUESDAY, NEARING 90 BY MID WEEK. TS
